The Violent Star Eta Carinae Model Is Based On Multiwavelength Observations
It was once one of the brightest stars in the heavens, easily visible to mariners navigating by the southern sky in the mid-1840s. But the star Eta Carinae quickly faded into obscurity after its brief outburst. Now, over a century and a half later, NASA space observatories (probing from infrared light through X-rays) have enabled astronomers and artists to assemble a three-dimensional model of the Homunculus Nebula and accompanying clouds of dust and gas enshrouding the petulant star. More than just an eye-catching visualization, the story of the 1843 Great Eruption and the history of the expelled nebula is designed to enrich astronomical learning, a key goal of NASA's Universe of Learning.
